Overview
The Mazak QT-Ez 10MY adds Y-axis capability to the milling-equipped 10-inch QT-Ez platform, enabling true off-center machining operations that would otherwise require a secondary setup on a vertical machining center. The MY configuration is the most popular in the QT-Ez 10 family for shops needing versatile mill-turn capability at a value price.
The QT-Ez 10MY runs a 254 mm (10 in) chuck with a maximum turning diameter of 343 mm (13.5 in) and a maximum turning length of 513 mm (20.2 in). The built-in motor spindle delivers 18.5 kW (25 hp) at up to 4,500 RPM. Bar capacity of 65 mm (2.56 in) covers standard production bar stock. The Y-axis provides approximately 100 mm of travel for off-center drilling, milling, and contouring operations.
The 12-position turret accepts bolt-on or BMT 55 tooling with live tools running at 6,000 RPM. C-axis resolution of 0.0001 degrees combined with the Y-axis enables complex milled features including flats, hexes, keyways, and off-center holes in a single setup. The BMT 55 interface delivers the rigidity needed for meaningful milling operations rather than just light drilling.
MAZATROL SmoothEz handles the 4-axis (X, Y, Z, C) programming with conversational and G-code support on a 15-inch touchscreen. The conversational interface simplifies Y-axis programming for operators who may not have extensive CAM experience.
The QT-Ez 10MY competes directly with the Haas ST-20Y, Doosan Lynx 2600MY, and Okuma LB3000 EX II MY. It delivers Mazak's motor spindle technology and MAZATROL control at pricing competitive with Korean and American alternatives. For shops producing parts with both turned and milled features within the 10-inch chuck range, the QT-Ez 10MY provides an excellent capability-to-cost ratio.

Strengths & Limitations
Strengths
- Y-axis enables off-center milling, drilling, and contouring for true mill-turn capability
- Built-in motor spindle eliminates belt vibration for superior surface finish
- BMT 55 turret provides rigid live tooling for meaningful milling operations
- MAZATROL SmoothEz simplifies Y-axis programming with conversational interface
- 0.0001-degree C-axis resolution matches higher-end Quick Turn models
- Mazak build quality at 20-30% below equivalent Quick Turn MY pricing
Limitations
- No sub-spindle for done-in-one processing; requires part flip for backworking
- SmoothEz lacks some advanced SmoothG simulation and optimization features
- 513 mm turning length limits longer shaft work
- Y-axis travel of 100 mm may constrain some off-center feature locations

Frequently Asked Questions
01
New pricing starts around $100,000 and reaches $155,000 with options like high-pressure coolant, parts catcher, and bar feeder interface.
02
The Quick Turn 200MY offers SmoothG control, more rigidity, and slightly more capacity but costs $30,000-$50,000 more. The QT-Ez 10MY delivers comparable capability for most work.
03
Approximately 100 mm total Y-axis travel, providing ample range for off-center drilling, milling, and contouring operations on most turned parts.
04
LNS, Iemca, FMB, and Hydrobar feeders are compatible. Bar capacity is 65 mm (2.56 in) through the spindle bore.
